*Measurements are from the bottom of the OP-HUB2 rack.
• Hub Racks are numbered sequentially, Rack1, Rack2, etc, or by serial number.
• Chassis in Hub racks are numbered by U number. For example, the lowest RF chassis
shown in Table 3-1 Would be numbered U12.
• BIM’s in racks are numbered by U number. For example, the lowest BIM shown in
Table 3-1 Would be numbered U8.
• Power Attenuators are located at the top of the Hub rack or mounted to a wall.
• WSP Base stations should be given unique Tenant Name and BTS ID designations.
• Each base station sector is cabled to a separate attenuator and BIM unit in the Hub
rack.
• Ensure that RF cables from the BIM forward output ports are connected to HDC
modules in its related HUB RF chassis.
• Ensure that RF cables from the BIM reverse input ports are connected to HUC
modules (primary to primary and diversity to diversity). Further ensure that any HUC
and HDC modules connected to a given BIM reside in the same Hub RF chassis.
